Referring to the drawings by characters of reference and more particularly to the form of the invention illustrated in Figs. 1 to 4 inclusive and Figs. 9 and 10, the window screen includes a panel indicated by the reference character A Which is fashioned of any desired material for diffusing or breaking up the glare of the light shining through the window. The panel A is supported I by a frame structure B for disposing the same in bowed inwardly extending relation in front of a window indicated by the reference character C to permit of the entrance of fresh air into the room when the window is open and to deflect the same upwardly and downwardly.

The frame structure B includes normally straight top and bottom bars HI and II and vertically disposed side stiles I2 and I3. As illustrated the side stiles l2 and I3 are of tubular formation and have studs 14 extending through the rolled ends I5 of the bottom bar H with the inner ends of the studs engaged in threaded openings in the lower ends of said side stiles for pivotally connecting the bottom bar therewith. Headed studs l6 slidably extend through the rolled outer ends I! of the top bar it) and have their inner ends slidably arranged in the upper open ends of the side stiles I2 and I 3 and are threadedly engaged by threaded adjusting ferrulesv 3- adapted when rotated with the lower ends thereof disposed against the upper ends of the side stiles to effect outward movement of the studs I6 to thereby move the top bar I8 away from the bottom bar II for accommodating different sizes of screens and for maintaining the same in a stretched or taut condition. When the adjusting ferrules I8 are turned in the opposite direction the top bar I is moved downwardly toward the bottom bar H to the position illustrated in Figs. 1, 2 and 3 of the drawings.

The side stile I2 is aflixed to the window frame at one side thereof by screws I9 or other equivalent fastening elements while the opposite side stile I3 is adapted to be releasably secured to the opposite side of the window frame by means of spring clips 20. When the side stile I3 is secured in position in the spring clips 20 the top and bottom bars I0 and II are disposed in bowed formation in front of the window as illustrated in Fig. 2 of the drawings to thereby tension the said bars whereby the same retain the bowed formation yet permit of flexing or bending thereof and when the side stile I3 is unlatched the said top and bottom bars return to their normal straight condition as illustrated in Fig. 1 and may be swung on the pivotal connection with the side stile I2 to dispose the window screen in an out-of-the-way position at one side of the window.

The side stiles I2 and I3 are disposed in vertical alignment and spacing elements 2I and 22 are provided through which respectively extend the screws I9 for connecting the side stile I2 to the window frame and screws 23 or equivalent fastening means for connecting the spring clips 29 to the opposite side of the window frame. By this construction the side stiles are maintained in equally spaced relation from the window frame when the screen is secured in bowed formation in front of the window. A handle 24 secured to the side stile I3 is provided for facilitating the latching of the side stile with the spring clips 29 and the unlatching of the same therefrom.

The panel A is provided with hemmed upper and lower edges 25 providing transversely extending tunnels in which are received the top and bottom bars I9 and II with the rolled ends projecting therefrom for mounting the panel on the frame structure B.

In the modified form of the invention illustrated in Figs. 5 to 8 inclusive of the drawings the window screen includes a panel similar to the panel A in the previous form of the invention and a frame structure indicated generally by the reference character D for supporting the panel thereon. The frame structure D consists of top and bottom bars 26 and 21 which may be made of any desired material such as sprin metal and the like and which are provided with rolled ends 28 defining vertical eyes similar to the top and bottom bars I 0 and II in the previous form of the invention. The frame structure D in this form of the invention also includes oppositely disposed vertical side stiles 29 and 30 constructed of flat sheet material having flanged outer side edges 3|, the side stile 29 being provided with a plurality of spaced apertures in which are received screws 32 or equivalent fastening means for securing the said side stile in vertical position against the window frame at one side thereof. The opposite side stile 30 is provided with a plurality of spaced keyhole slots 33 adapted to receive enlarged heads of fastening elements 34 secured to the window frame for releasably fastening the said side stile in vertical alignment with the side stile 29 and on the opposite side of the window therefrom.

The side stiles 29 and 39 are each provided with a yoke 35 secured thereto at their upper ends which are formed with vertically aligned apertures in the upper and lower ears 36 thereof in which are mounted threaded shanks 31 secured against rotation by the threaded nuts 38. The top bar 26 is mounted for movement on the threaded shanks 31 for adjustin the same toward and away from the bottom bar 21 so as to accommodate different heights of screens and to maintain the same in taut condition. The threaded shanks 3'I slidably extend through the eyes defined by the rolled ends 28 and threaded adjusting ferrules or nuts 39 threadedly engage the shanks below the top bar 26 for elevating or lowering the same by rotation of the said adjusting nuts. The bottom bar 21 is secured to the lower ends of the side stiles 29 and 30 by means of studs 40 extending through the eyes defined by the rolled ends 28 thereof and apertured ears of yokes 4I secured to the outer faces of said side stiles. The panel is hemmed at its up er and lower ends similar to the panel A in the previous form of the invention to provide tunnels in which the top and bottom bars 26 and 21 are slidably received with the rolled ends 28 projecting therefrom at the oposite ends for mounting the panel on the frame structure D.

By this construction the frame structure D together with the panel mounted thereon may be latched in front of the window in inwardly bowed formation and when the side stile 30 is unlatched the frame structure may be swung to an out-ofthe-way position at one side of the window with the upper and lower bars 26 and 21 disposed in straightened relation.

In the modified form of the invention illustrated in Figs. 11 to 14 inclusive of the drawings, the window screen includes a frame structure indicated generally by the reference character E for supporting a panel similar to the panel A in the previous forms of the invention. The frame structure E consists of top and bottom bars 43 and 44 having rolled ends defining vertical eyes 45 similar to the top and bottom bars in the previous forms of the invention. The frame structure E also includes oppositely disposed vertical side stiles 46 and 41 having reduced threaded lower ends 48 engaging through the vertical eyes 45 of the lower bar 44 which is secured thereon by the nuts 49 engaging the protruding ends of the reduced portions 48. The upper ends of the side stiles 4'6 and 41 are formed with vertical bores 59 in which bars 5| are slidably mounted and adapted to be secured in adjusted position by the tightening of wing screws 52 protruding through slots 53 in the said side stiles and engaging through threaded apertures 54 in the bars 5|. The inner ends of the said wing screws 52 are adapted to be tightened against the inner face of the bore 50 of the said side stiles for securing the bars 5I in adjusted position. The bars 5I have reduced threaded upper ends 52 engaging through the vertical eyes 45 of the top bar 43 which is secured thereon by means of nuts 53 threadedly engaging the protruding ends of the reduced portions 52.

The frame structure E is adapted to be removably secured in front of a window-with the top and bottom bars 43 and 44 bent into resilient bowed formation. For this purpose the side stile 4 6 is adapted to be latched to one side of the window frame indicated generally by the reference character F in Fig. 11 of the drawings by means of headed fastening elements 55 engaging through bayonet slots 66 in offset brackets 57 secured by screws or other means to the window frame. The opposite side stile 87 is adapted to be latched to the opposite side of the window frame by means of spring clips 58 similar to the spring clip 29 in the previous form of the invention. A handle 59 secured to the side stile i? is provided for manually grasping the frame when the same is to be disposed in latched engagement with the spring clips 58 .or unlatched therefrom and swung to a position at one side of the window.
